OK, a couple of weeks ago I was down at a friends shop, we were timing and lashing valves on some trucks, and this one kid with a 96 took off his afc housing and cut the foot off of the lever!, what does this actually do? I have heard of something like that for the 1st gens, but is this any help for the 2nd gens? anybody enlighten me?

I would also like to know the answer to that one. I have heard of people taking the complete arm and spring out.

The AFC assembly is just another throttle stop with in the pump. Boost pressure moves the the AFC throttle stop out of the way of the governor arm and lets your fuel cam plate be the final throttle stop that the governor arm can follow. As long as your AFC housing is full forward and there is not excessive spring tension, the AFC throttle stop will move out of the way of the governor arm at a reasonable boost level and certainly will not limit ultimate fueling. The AFC is a good tool for tuning smoke levels and low boost throttle response. Removing the throttle stop will just produce much more low boost smoke and egt and will not gain anymore power over a properly tuned AFC.
you'll smoke very badle doing that and your fuel economy will plumet in stop n go driving...and if ur friend has cat on his truck then happy pluggin and unhappy egts
